It's more about shape than anything but an ass like that is indicative of zero muscle development - and I'm not asking for a firm athletic ass, I like fat bitches and I know they can't run, but absolutely zero means she can't even fuck right and there's nothing fun about that. This in turn makes the weird melting ass even less attractive. It's a fat man's ass.
